综采工作面内由于受地质条件限制,在切眼附近工作面呈大倾角仰采布置,平均仰采角度38度,最大仰采角度达42度,如何进行综采工作面大倾角仰采是一个我们研究的技术课题。介绍了长城矿1303面概况及综采工作面大倾角仰采工艺实践,分析了解决生产过程的技术关键及具体办法,并总结了综采工作面大仰角开采工艺研究成果及其推广应用价值。
Due to the limitation of geological conditions in fully mechanized coal mining face, the working face near the cut-out shows a large angle of Yang mining layout, the average Yang mining angle of 38 degrees, the maximum Yang mining angle of 42 degrees, A technical project we studied. The general situation of 1303 face of Changcheng Mine and the practice of Yangjian mining with large dip angle in fully mechanized mining face are introduced. The technical key and specific measures to solve the production process are analyzed. The research results and application of large elevation mining technology in fully mechanized mining face are summarized.
